biting ans aggressive behavior

[Giselle]

If your brother in law is a behaviorist, you need to be working with him full time. We absolutely can not, in good ethics, give you any advice on this situation over the Internet.

This is serious. You need to be working with a professional behaviorist AND a veterinarian because, yes, it does sound neurological and deeply psychological. Good luck.

I totally agree with Giselle....he sounds like he is probably in a lot of pain whether it be physical or not.....I would be so scared he would bite someone.....that could be a financial disaster for you if you were sued.
